HitTesterHitTest(Ray, Vector3, Int32, Boolean, Int32, Boolean, Single) Method

public static RayHitTestResult? HitTest(
	Ray localRay,
	Vector3[]? positionsArray,
	int[]? indexBufferArray,
	bool hitOnlyFrontFacingTriangles,
	int startTriangleIndex,
	bool getOnlyNextHitTest,
	float zeroTolerance = 1E-07f
)

Parameters

localRay  Ray

ray transformed to local coordinate system

positionsArray  Vector3

vertex buffer as array of Vector3

indexBufferArray  Int32

index buffer

hitOnlyFrontFacingTriangles  Boolean

When true then only triangles that have normals (calculated from triangle positions) oriented in the opposite direction as the ray are returned (because ray is usually created from the camera's position this returns only triangles that are facing the camera).

startTriangleIndex  Int32

index of the triangle where the hit testing will begin - triangle indice index is get by multiplying this number by 3

getOnlyNextHitTest  Boolean

when true, then the next hit result is returned; when false all hit results are get and only the closest to the ray origin is returned.

zeroTolerance  Single  (Optional)

optional float that defines the zero tolerance - if value is smaller that this value, then it is considered zero. It is recommended that this value is based on the mesh's size. Default value is 1e-7.
